Description

TECHNICAL FIELD

[0002] Power secondary equipment includes relay protection equipment, measurement and control equipment, power distribution protection and control equipment. The data of the equipment includes different types such as input, output, remote signaling, remote measurement, remote control, remote adjustment, and parameters. The contents of various types of data are different. In addition, the data structure of the same type of equipment will also change due to different service objects and application scenarios. The data of the power secondary equipment needs to be stored in the memory of the equipment, and can be read, displayed and remotely transmitted through display software, communication software, etc. It can also be debugged and configured using tool software.

[0003] Due to the limited storage space, the protection and control CPU of the power secondary equipment cannot use database technology for data storage and access. Usually, when designing product software, according to the characteristics of service objects and application scenarios, the structure of various types of data is designed, and the variables of the structure are agreed to be used for display, communication and configuration, etc. The related software stores and reads and writes the data according to the agreement. Due to the different service objects and application scenarios of each product, the data structure definition needs to be adjusted accordingly, so that the device software and tool software of different products are different, and the development, testing and maintenance workload is huge.

[0004] For equipment that cannot use a database due to limited storage space, different data structures need to be designed for different types of data. When designing product software, according to the characteristics of service objects and application scenarios, the structure of various types of data is designed, and the corresponding variable attributes of the structure are agreed to be used for display, communication, and tool configuration. The related software stores and reads and writes the data according to the agreement, which makes the device software and tool software of different products cannot be effectively reused; when the product software is upgraded due to changes in product function requirements, the structure of the same type of data will also change, and some designs increase the memory overhead by adding spare attributes for compatibility, which affects the read and write efficiency of storage; the above factors result in large development and testing workload of product software. At the same time, due to the existence of different types of equipment in the service environment, as well as the software of the same type of product in different periods and different versions, the debugging and configuration tool software needs to start different branch programs according to the equipment category, and the branch tool software of the same type of equipment also needs to be compatible with the equipment in different periods through version information, so the development and maintenance of the tool software also become complex.

[0038] In view of the deficiencies of the prior art, the present application provides a lightweight power secondary equipment data access method and system, which establishes a data type table, unifies a data structure header, defines a data table configuration rule, and tool software displays and operates various data tables according to the data configuration rule, converts the data storage structure and data content according to the data configuration rule, defines a unified data access interface of the power secondary equipment software, realizes flexible access of various data variables, is used for public modules such as communication and display processing, and is compatible with the tool software through the data table configuration rule.

The device software module accesses various data through a unified interface, and the compact data structure is suitable for the power secondary equipment with limited storage space; the tool software simultaneously satisfies flexible display, configuration, conversion of various data, and a set of tool software is suitable for different devices and different versions.

[0039] Referring to Figure 1 The lightweight power secondary equipment data access method disclosed by the present application comprises the following steps:

[0040] Step 1: defining all data types of the power secondary equipment data to form a data type table.

[0041] In a specific embodiment, the data type table is defined as follows:

[0042]

[0043] XML format text of the data type table:

[0044] <TlvTable name="data type">

[0045] <Content ID="1" tag="1" key="Boolean" name="Boolean" size="1" / >

[0046] <Content ID="2" tag="43" key="Tiny" name="Tiny" size="1" / >

[0047] <Content ID="3" tag="32" key="UTiny" name="UTiny" size="1" / >

[0048] <Content ID="4" tag="33" key="Short" name="Short" size="2" / >

[0049] <Content ID="5" tag="45" key="UShort" name="Unsigned Short" size="2" / >

[0050] <Content ID="6" tag="2" key="Int" name="Int" size="4" / >

[0051] <Content ID="7" tag="35" key="Uint" name="Unsigned Int" size="4" / >

[0052] <Content ID="8" tag="36" key="Long" name="Long" size="8" / >

[0053] <Content ID="9" tag="37" key="Ulong" name="Unsigned Long" size="8" / >

[0054] <Content ID="10" tag="38" key="Float" name="Float" size="4" / >

[0055] <Content ID="11" tag="39" key="Double" name="Double" size="8" / >

[0056] <Content ID="12" tag="8" key="OcterString" name="Octet String" size="8" / >

[0057] <Content ID="13" tag="4" key="String" name="String" size="64" / >

[0058]

[0059] Step 2: Define the structure header according to the index number of the power secondary equipment data, the data name, the data type in the data type table, the data length, the data quality and the data value.

[0060] By defining the header of all data structures, all types of data are directly and uniformly processed simply. In a specific embodiment, the data table data structure header is defined as follows:

[0061]

[0062] The corresponding structure is:

[0063]

[0064]

[0065] Step 3: Use XML format to define data table configuration rules, which include ID, key name, column name, table width, display mode and conversion rule.

[0066] By implementing flexible definition of different data tables, the tool software uses a unified table processing module to adapt to different products and different types of data tables. The conversion rule transTlv corresponds to the tag field of TlvTable.

[0067] Example 1: Configuration of incoming table of power secondary equipment

[0068] <DIConfig Table="DITable" name="Incoming configuration">

[0069] <Content ID="1" key="index" title="Index number" width="5" display="number" transTlv="35" / >

[0070] <Content ID="2" key="name" title="Name" width="32" display="string" transTlv="4" / >

[0071] <Content ID="3" key="datatype" title="Data type" width="9" display="list" listtable="TlvTable" transTlv="43" / >

[0072] <Content ID="4" key="datalen" title="Data length" width="5" display="number" transTlv="43" / >

[0073] <Content ID="5" key="quality" title="Quality" width="5" display="hex" transTlv="32" / >

[0074] <Content ID="6" key="value" title="Value" width="5" display="number" transTlv="1" / >

[0075] <Content ID="7"key="board"title="板卡号"width="5"display="number"transTlv="32" / >

[0076] <Content ID="8"key="order"title="开入号"width="5"display="number"transTlv="32" / >

[0077]

[0078] Example 2: Remote control meter configuration for power secondary equipment:

[0079] <CtrlConfig Table="CtrlTable"name="遥控配置">

[0080] <Content ID="1"key="index"title="索引号"width="5"display="number"transTlv="35" / >

[0081] <Content ID="2"key="name"title="名称"width="32"display="string"transTlv="4" / >

[0082] <Content ID="3"key="datatype"title="数据类型"width="9"display="list"listtable="TlvTable"transTlv="43" / >

[0083] <Content ID="4"key="datalen"title="数据长度"width="5"display="number"transTlv="43" / >

[0084] <Content ID="5"key="quality"title="品质"width="5"display="hex"transTlv="32" / >

[0085] <Content ID="6"key="value"title="值"width="5"display="number"transTlv="1" / >

[0086] <Content ID="7" key="board" title="Control point number" width="5" display="number" transTlv="32" / >

[0087]

[0088] Step 4: Based on the data table configuration rules, display and configure the data table in the tool software.

[0089] In Example 1, the opening configuration table is displayed as:

[0090]

[0091] In Example 2, the remote control configuration table is displayed as:

[0092]

[0093] Step 5: Based on the data table configuration rules and the defined structure header, generate the structure and corresponding data in the tool software.

[0094] According to the conversion rule transTlv in the data table configuration rule, the corresponding structure is automatically formed, and the values in the table are converted to structure data, so that the tool is flexible and compatible with different products and different types of data, and is automatically converted to the data structure and its numerical value consistent with the device, without secondary processing in the device.

[0095] In Example 1, according to transTlv in DIConfig, the opening configuration data storage structure is converted to:

[0096]

[0097] In Example 1, the table is converted to the opening table structure data, which is downloaded to the corresponding opening table configuration data in the device:

[0098]

[0099] In Example 2, according to transTlv in CtrlConfig, the remote control configuration data storage structure is converted to:

[0100]

[0101]

[0102] In Example 2, the table is converted to the opening table structure data, which is downloaded to the corresponding opening table configuration data in the device:

[0103]

[0104] Step 6: Define a unified data access interface for reading the value of data according to the index number, data type or data length in the structure.

[0105] The first five attributes of the structure tTableHead of different tables are the same, and the sixth attribute value is corresponding to the data type according to datatype, and the storage space size is allocated according to datalen; therefore, the functions of communication and display in power secondary equipment can access the name and value of different types of data through the same interface;

[0106] The structure head of different products and different types of data is defined the same, and the common software modules of communication, display and the like correctly access the data through the data access interface, reuse the common module code, and do not need to modify the code. This step makes the communication, display and the like of the common software modules of the equipment be designed universally, adapt to the configuration of different types of data and different versions, and do not modify the common software modules due to different service objects and application scenarios of products.

[0107] Step 7: Based on the data access interface, the communication software of the power secondary equipment accesses different data values according to the data type, which is used for communication between the equipment and the monitoring system, or transmission to the debugging tool for dynamic display of numerical values.

[0108] Step 8: Based on the data access interface, the display software of the power secondary equipment accesses the data name and data value according to the data type, which is used for displaying the current equipment data locally.

[0109] In Example 1, the local display of the incoming table is as follows:

[0110]

[0111] In Example 2, the local display of the remote control table is as follows:

[0112]

[0113] The application has the advantages that, compared with the prior art, the application provides a lightweight power secondary equipment data access method and system, and device public software modules are highly reused; the communication, display and other public software modules of the device are designed universally, and are suitable for different data types, different versions, different products, different service objects and different application scenarios; the compact data structure is suitable for power secondary equipment with limited storage space; the lightweight structured data saves the memory resources of the device and has a high data processing speed; various data tables are automatically converted into data structure bodies and corresponding parameters in the device through conversion rules; the device directly uses the data converted by the tool according to the structure body, and does not need to be processed again; the designed tool software can simultaneously meet the flexible display, configuration and conversion of various data, and a set of tool software is suitable for different devices and different versions.
